Ravi Prakash commented on HADOOP-12117:
---------------------------------------
Thanks for the contribution Zhihai! setAllowNullValueProperties seems to have
been added to support unit test cases downstream. Is there a unit test case you
can point me to which is causing this?
I'd be wary of opening up the access level of a Configuration method (even if
it is labeled @VisibleForTesting) . Are you sure we can't unit test without
changing the access level?
Also please log the exception in testLoadProperty().

> The following code will cause NPE:
> {code}
> } else if (!value.equals(properties.getProperty(attr))) {
> {code}
> Because if {{allowNullValueProperties}} is true, {{value}} is null and
> {{finalParameters}} contains {{attr}}, NullPointerException will happen
